Shrub rose plant named ‘WEKyoopedko’

ABSTRACT

A new variety of Shrub rose suitable for garden decoration, having flowers of red with lighter reverse coloration with a white ‘eyezone’.

Classification: The present invention relates to a new Rosa hybrida plant.

Variety denomination: The new plant has the varietal denomination ‘WEKyoopedko’.

BACKGROUND OF THE INVENTION

This invention relates to a new and distinct variety of Shrub Rose. It has as its seed parent the variety known as ‘WEKiscorou’ (not patented) and as its pollen parent the variety known as ‘RADtko’ (U.S. Plant Pat. No. 16,202).

SUMMARY OF THE INVENTION

Among the features which distinguish the new variety from other presently available and commercial rose cultivars known to the inventor are the following combinations of characteristics: its high degree of resistance to black spot, powdery mildew, downy mildew and rust, its excellent color stability throughout the life of the flower and its rough peduncle with many stipitate glands and some small prickles. The plant has an upright bushy growing habit, suitable for outdoor garden decoration.

Asexual reproduction of the new variety by budding as performed in Kern County and Pomona, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding asexual propagations. ‘WEKyoopedko’ may be asexually propagated by cuttings, budding and grafting. The budding and grafting successfully occurred on the plant/rootstock Rosa hybrida cv. Dr. Huey (not patented).

COMPARISON WITH PARENTS

The new rose may be distinguished from its seed parent, ‘WEKiscorou’ by the following combination of characteristics: whereas ‘WEKyoopedko’ bears flowers of red with lighter reverse coloration with a white ‘eyezone’, ‘WEKiscorou’ bears flowers of scarlet coloration with a white reverse. The new variety has an upright bushy medium height growing habit (about 110 to about 142 cm. in height), whereas the seed parent has a compact rounded significantly shorter growing habit (about 30 to about 45 cm. in height).

The new variety may be distinguished from its pollen parent, ‘RADtko’ by the following combination of characteristics: whereas ‘WEKyoopedko’ bears flowers of red with lighter reverse coloration with a white ‘eyezone’, ‘RADtko’ bears flowers of red coloration. The new variety has an upright bushy medium height growing habit (about 110 to about 142 cm. in height), whereas the pollen parent has a rounded bushy significantly shorter growing habit (about 90 to about 120 cm. in height).

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The closest commercially available cultivar to the new variety is the pollen parent ‘RADtko’ (U.S. Plant Pat. No. 16,202).

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph illustrates the new variety and shows the flowering thereof from bud to full bloom depicted in color as nearly correct as it is possible to make in a color illustration of the character.

The branches used for the photograph came from 3 to 4 year-old rose plants of the new variety grown outdoors in Wasco, Calif. in the month of October.

Throughout this specification, color references and/or values are based upon the Colour Chart of The Royal Horticultural Society (1966) except where common terms of color definition are employed.

DESCRIPTION OF THE NEW VARIETY

The following description is of 3 to 4 year-old rose plants of the new variety grown outdoors in Wasco, Calif. in the month of October. Phenotypic expression may vary with environmental, cultural and climatic conditions, as well as differences in conditions of light and soil.

FLOWER

The new variety sometimes bears its flowers singly, usually in clusters of two to four per stem. Flowers may be borne in regular rounded clusters on strong somewhat short to medium length stems (about 18 to about 65 cm.). Outdoors, the plant blooms abundantly and nearly continuously during the growing season. The flowers have a slight tea fragrance.

BUD

The peduncle is about 2.1 to about 5.8 cm. in length, of moderately heavy caliper (about 0.2 to about 0.3 cm. in diameter), and usually erect. It is rough, with many stipitate glands and some small prickles. Peduncle color is between 144A and 146C often heavily suffused, especially on the side exposed to the sun, with between 187B and 187A.

Before the calyx breaks, the bud is about 0.8 to about 1.5 cm. in diameter at the widest point, about 1.4 to about 1.8 cm. in length, and pointed to somewhat ovoid in shape. The surface of the bud bears between 6 to 12 foliaceous appendages and some stipitate glands, usually with slender moderately cut foliaceous parts extending beyond the tip of the bud about ½ or more of its length. Bud color is between 137C and 146C often heavily suffused, especially on the side exposed to the sun, with between 187A and 187B.

The sepals are about 2.0 to about 2.7 cm. in length and about 0.6 to about 0.8 cm. in width at the widest point. The outer surface color of the sepal is between 137C and 146C often heavily suffused, especially on the side exposed to the sun, with between 187A and 187B. The outer surface of the sepal is somewhat rough and bears between 0 to 5 foliaceous appendages with some stipitate glands. The inner surface color of the sepal is near 146C broadly bordered by near 137B. After the sepals open, the inner surface color is often moderately suffused, especially on the area exposed to the sun, with between 187A and 187B. The inner surface of the sepal is covered with fine wooly tomentum; sepal margins are lined with some stipitate glands and many hairs.

The receptacle of the flower is of medium length (about 0.5 to about 0.7 cm.) and average in caliper (about 0.6 to about 0.8 cm. in diameter). The receptacle is urn-shaped in form. Its surface is smooth with moderately thick fleshy walls. The receptacle color is between 144A and 146C.

As the petals open (after the calyx breaks), the bud is about 1.5 to about 1.9 cm. in diameter at the widest point, about 1.9 to about 2.3 cm. in length, and ovoid to somewhat pointed in form. The color of the under surfaces of the newly opened petals is between 53A and 53B. At the point where the petal attaches, there is a large zone of between 1C and 154C. The color of the upper surfaces of the newly opened petals is between 187A and 187B. At the point where the petal attaches, there is a large zone of between 1C and 154C.

BLOOM

When fully open, the bloom ranges from about 5.6 to about 8.9 cm. in diameter. Petalage is double with about 15 to 24 petals and about 2 to 6 petaloids irregularly arranged. When partially open, the bloom form is high centered to somewhat cupped, and the petals are moderately tightly spiraled to somewhat cupped with petal edges somewhat reflexed outward. When fully open, the bloom form is more cupped, and the petals are loosely cupped to somewhat undulated with petal edges moderately reflexed outward.

PETALS

The substance of the petals is heavy and of moderately thick thickness, with upper surfaces moderately satiny to somewhat velvety and under surfaces slightly shiny. The petals are about 2.8 to about 4.3 cm. in length and about 2.4 to about 4.4 cm. in width at the widest point. Petal margins are entire.

The outer petals are somewhat obovate to nearly round in shape with rounded apices.

The inner petals are moderately obovate in shape with rounded apices.

Petaloids are about 1.0 to about 3.7 cm. in length and about 0.5 to about 2.4 cm. in width at the widest point. Petaloids are irregularly shaped moderately oblanceolate to somewhat obovate with rounded apices.

NEWLY OPENED FLOWER

The under surface color of the outer, intermediate and inner petals is between 155A and 155B often moderately to heavily suffused with between 53B and 53C. At the point where the petal attaches, there is a large zone of between 155A and 155B. The upper surface color of the outer, intermediate and inner petals is between 53B and 45B. At the point where the petal attaches, there is a large zone of between 2D and 1D.

The under and upper surface colors of the petaloids are similar in coloration to the upper and under surfaces of the intermediate and inner petals.

The general tonality of the newly opened flower is between 53B and 45B.

THREE-DAY-OLD FLOWER

The under surface color of the outer, intermediate and inner petals is between 155A and 155B often moderately to heavily suffused with between 60B and 53C. At the point where the petal attaches, there is a large zone of between 155A and 155B. The upper surface color of the outer, intermediate and inner petals is between 53B and 45B. At the point where the petal attaches, there is a large zone of between 155A and 4D.

The under and upper surface colors of the petaloids are similar in coloration to the upper and under surfaces of the intermediate and inner petals.

The general tonality of the three-day-old flower is between 53B and 45B.

On the spent bloom, the petals usually drop off cleanly.

In October in Wasco, Calif., blooms on the bush growing outdoors generally last about four to five days. Cut roses from plants grown outdoors and kept at normal indoor living temperatures generally last about four to five days.

MALE REPRODUCTIVE ORGANS

Stamens are many in number (average about 150) and are arranged regularly about the pistils; a few are mixed with petaloids. The filaments are of somewhat short to medium length (about 0.5 to about 1.2 cm.) most with anthers. Filaments are between 154D and 1D in color. The anthers are moderately small for the class and all open approximately at the same time. Anther color when immature is near 22A on the external part and near 78D on the internal part.
